Summary

The thesis for Ph. D. degree is dedicated to theoretic substantiation and research of the involvement of innovation factor in the assessment of investments’ efficiency through studies regarding the innovation as a factor for increasing the efficiency of investments and as a determinant in chain development of branches of economy through relations that exists between them. The interindustry technological dependence was the basis for elaborated method and proposals regarding a new approach of evaluation of efficiency innovation investments.

The study’s basis is the investigation of peculiarities of the assessment of efficiency of investments in innovation and the complex analysis of effects of innovation allowed to approach the assessment of the investments’ in innovation efficiency by interindustry technological dependencies, making up an algorithm and a economic - mathematical model for the evaluation of investments’ in innovation efficiency.

A special attention is paid to input – output model as an efficient instrument to analyze the existing relations between branches of an economy and to follow the technological changes due to one of the most important factor – technological innovations.

An important place is dedicated to interindustry technological dependencies method that can evaluate the innovation efficiency taking into account the innovation effects in the main branch, that in which the innovation was implemented and also the premises for important effects generated by innovation in other related branches. Following this idea was developed an algorithm that included to elaborate the mathematic model of optimization, with purpose function to maximize the total return on innovation, obtained as in the main branch as in related branches, in conditions of limiting of investment costs generated by the implementation of innovation.

The research results have a conceptual and equipped aspect and can be implicated in elaborating strategies and adopting decisions of economic agents that promote innovation, as well in establishing objectives of state policy regarding stimulating the innovatory activity and also in the didactic contributing to completing the theory and practice of the assessment of investments’ efficiency.
